Hi, do you have availability tomorrow?
Hi! 👋 Sure. These are tomorrow’s slots:
🕘 9:00 a.m. 🕚 11:30 a.m. 🕓 4:00 p.m.
11:30 please
✅ Done, your appointment is booked. I’ll send you a reminder 1 hour before.
Sound familiar?

What is costing you customers and time

💬

You answer the same things all day

Prices, hours, location, payment methods… the same questions eat your team’s time.

🌙

You lose customers after hours

If someone writes at 10 p.m. and nobody answers, they buy from your competitor.

📋

Orders and bookings by hand

Collecting data by chat, copying it to Excel and confirming one by one causes errors and delays.

🔌

Systems that don’t talk

Your store, spreadsheet, CRM and chat live apart, and someone has to move the data.

Solutions

What I build for your business

For now I specialize in two channels, WhatsApp and Telegram, plus the automations that connect them to the rest of your operation.

WhatsApp Chatbot

Serve, sell and book on the channel your customers already use, through the official WhatsApp Business API.

  • Menus and automatic answers to frequent questions.
  • Order taking, quotes and appointment booking.
  • Automatic reminders and confirmations.
  • Hand-off to a human agent when the customer needs it.
  • AI answers trained on your business information.

Telegram Bots

Great for communities, internal teams and alerts: no per-message cost and very flexible.

  • Real-time alerts: sales, low stock, system outages.
  • Automatic daily reports sent to your group or channel.
  • Commands to check your business data from your phone.
  • Community, subscription and content management.

Process Automation

I connect your tools so data flows on its own and your team focuses on what creates value.

  • Integration with Google Sheets, databases, CRMs and APIs.
  • Automatic web data extraction (prices, catalogs, competitors).
  • Scheduled tasks: data cleaning, backups, reports.
  • Secure deployment on your own server with Docker and monitoring.

FAQ

Do I need a new number for the WhatsApp bot?

A dedicated number is recommended, because once it is connected to the official WhatsApp Business API it can no longer be used in the regular app. I guide you through registration and verification with Meta.

Does WhatsApp charge for messages?

Meta charges its current rates for template messages started by the business (promotions, reminders). Replying to customers who message you within the service window is free or very low cost. I give you an estimate based on your volume before we start.

What about Telegram?

The Telegram Bot API is free. You only pay for the server the bot runs on, which is usually inexpensive.

Can the bot hand the conversation to a person?

Yes. When the customer asks or the bot doesn’t know the answer, it notifies your team and an agent takes over.

Do you have something affordable to start?

Yes. Simple automations (a Telegram alert bot, a reminder, an automatic daily report) start at $25 USD. It is a good way to try it out before automating bigger processes.

How long does it take?

An express automation takes 2 to 5 days. A support bot takes 1 to 2 weeks. Bots with integrations or custom automations take 3 to 5 weeks depending on scope.

What happens after delivery?

A support period is included. After that you can hire a monthly maintenance plan with tweaks, monitoring and improvements.
